Description

Technical Field

[0001] This utility model relates to the field of television back panel technology, and in particular to a television back panel with a heat dissipation structure. Background Technology

[0002] The back panel of a television is a core component, serving as a crucial structure that houses various internal electronic components (such as the motherboard, power module, and display driver components). It also plays a vital role in protecting these components and maintaining the overall stability of the television. As televisions become thinner, lighter, higher-definition, and more intelligent, the integration of their internal components increases significantly, leading to a substantial rise in heat generated during operation. Therefore, the heat dissipation performance and structural stability of the back panel directly impact the television's operating efficiency, lifespan, and safety, making it a key indicator of a television's product quality.

[0003] In existing technologies, heat dissipation for television back panels mostly employs natural cooling or simple passive cooling structures. For example, some back panels use heat dissipation fins on the surface to dissipate heat to the outside through natural air convection; others install small cooling fans inside the back panel to directly blow air onto the components for cooling. The underlying principle relies primarily on natural airflow or forced airflow from a single fan, achieving cooling through direct heat exchange between the components and the air. Regarding structural protection, traditional back panels typically use a one-piece rigid structure, or simply increase the back panel thickness to improve impact resistance, relying on the inherent strength of the material to withstand external forces.

[0004] However, the heat dissipation efficiency of the back panel of a television in the current technology is relatively low and difficult to maintain in a stable manner over a long period of time. On the one hand, natural heat dissipation or airflow from a single fan is insufficient to quickly remove the large amount of heat generated by highly integrated components, which can easily lead to excessively high internal temperatures of the television, affecting component performance or even causing damage. On the other hand, although some heat dissipation structures are equipped with filter components, the disassembly and assembly process is cumbersome, making it inconvenient to clean or replace them regularly. After long-term use, the filter components are prone to clogging, further reducing the heat dissipation effect and failing to ensure the continuous and stable operation of the heat dissipation system. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a TV back panel with a heat dissipation structure, aiming to improve the problem that the heat dissipation efficiency of the TV back panel in the prior art is low and it is difficult to maintain long-term stability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a television back panel with a heat dissipation structure, comprising an outer shell, a connecting plate provided on one side of the outer wall of the outer shell, a ventilation assembly provided inside the connecting plate, a fixing plate fixedly connected inside the outer shell, a cooling water tank fixedly connected to the inner wall of the fixing plate, a circulating water pipe fixedly connected inside the cooling water tank, heat sinks fixedly connected to the outer wall of the circulating water pipe, a fan fixedly connected to the inner wall of the fixing plate, a filter plate provided on the outer wall of the fan, a locking block slidably connected inside the fixing plate, a telescopic rod fixedly connected inside the locking block, and a spring sleeved on the outer wall of the telescopic rod.

[0007] The ventilation assembly includes ventilation holes, which are formed inside the connecting plate, and a filter screen is fixedly connected inside the outer casing.

[0008] Furthermore, a guide plate one is fixedly connected to the top of the outer shell, and a guide plate two matching the guide plate one is fixedly connected to the top of the connecting plate.

[0009] Furthermore, limiting plates are fixedly connected to both sides of the outer wall of the outer shell, and the connecting plate is slidably connected to the inner wall of the limiting plates.

[0010] Furthermore, a telescopic rod two is fixedly connected between the outer shell and the connecting plate, and a spring two is sleeved on the outer wall of the telescopic rod two.

[0011] Furthermore, one end of the second spring is fixedly connected to one side of the outer wall of the outer casing, and the other end of the second spring is fixedly connected to one side of the outer wall of the connecting plate.

[0012] Furthermore, the outer wall of the filter plate is slidably connected to the outer wall of the fixed plate.

[0013] Furthermore, the outer wall of the card block is slidably connected to the inside of the filter plate, and the outer wall of the heat sink is fixedly connected to the inner wall of the fixed plate.

[0014] Furthermore, one end of the spring is fixedly connected to the inside of the card block, and the other end of the spring is fixedly connected to the inside of the fixing plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, air driven by a fan enters the outer casing after being filtered by a filter plate. Combined with cooling water transported by a circulating water pipe and heat sink, it forms a highly efficient heat dissipation combination. It can quickly dissipate the heat inside the TV through heat exchange, effectively preventing components from being damaged by high temperature. It is convenient to clean or replace regularly to maintain the filtration effect, ensure the long-term stable operation of the heat dissipation system, and extend the service life of the TV.

[0017] 2. In this utility model, the second spring between the outer shell and the connecting plate can effectively buffer external forces, and the second telescopic rod plays a precise guiding role. Together with the sliding limit of the second guide plate on the outer wall of the first guide plate and the auxiliary guidance of the limit plate, a multi-protection structure is formed, which can greatly reduce the impact of external collisions, vibrations and other external forces on the internal components of the television set, and improve the structural safety and reliability of the product during use.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 - Figure 6An embodiment of this utility model provides a TV back panel with a heat dissipation structure, including an outer shell 1, a connecting plate 14 provided on one side of the outer wall of the outer shell 1, a ventilation component provided inside the connecting plate 14, a fixing plate 4 fixedly connected inside the outer shell 1, a cooling water tank 5 fixedly connected to the inner wall of the fixing plate 4, a circulating water pipe 6 fixedly connected inside the cooling water tank 5, a heat sink 7 fixedly connected to the outer wall of the circulating water pipe 6, a fan 8 fixedly connected to the inner wall of the fixing plate 4, a filter plate 9 provided on the outer wall of the fan 8, a locking block 10 slidably connected inside the fixing plate 4, a telescopic rod 12 fixedly connected inside the locking block 10, and a spring 11 sleeved on the outer wall of the telescopic rod 12.

[0028] The ventilation assembly includes a ventilation hole 2, which is opened inside the connecting plate 14. A filter screen 3 is fixedly connected inside the outer shell 1. The outer wall of the filter plate 9 is slidably connected to the outer wall of the fixed plate 4. The outer wall of the locking block 10 is slidably connected to the inside of the filter plate 9. The outer wall of the heat sink 7 is fixedly connected to the inner wall of the fixed plate 4. One end of the spring 11 is fixedly connected to the inside of the locking block 10, and the other end of the spring 11 is fixedly connected to the inside of the fixed plate 4.

[0029] Specifically, when using the TV back panel, first start the fan 8 to draw outside air into the outer casing 1. During this process, the air is first filtered by the filter plate 9 to prevent dust and other debris from damaging internal components. When the filter plate 9 needs cleaning or replacement, press the latch 10 to allow it to slide between the fixing plate 4 and the filter plate 9, and apply pressure to the spring 11 to retract it. Once the latch 10 is fully inserted into the inner wall of the fixing plate 4, the filter plate 9 can be removed. During installation, return the filter plate 9 to its original position; the spring 11 will spring back, pushing the latch 10 back into the filter plate 9, completing the disassembly and assembly. The filtered air continues to be supplied, cooled by the heat sink 7, and then sent into the outer casing 1. During this process, the circulating water pipe 6 supplies cooling water from the cooling water tank 5, ensuring the cooling water is evenly distributed within the heat sink 7 to maintain its cooling state. Finally, the air inside the outer casing 1, after heat exchange, is discharged through the ventilation hole 2, achieving cooling and heat dissipation for the TV.

[0030] Reference Figure 1 - Figure 6 A guide plate 13 is fixedly connected to the top of the outer shell 1, and a guide plate 15 matching the guide plate 13 is fixedly connected to the top of the connecting plate 14. Limiting plates 16 are fixedly connected to both sides of the outer wall of the outer shell 1. The connecting plate 14 is slidably connected to the inner wall of the limiting plate 16. A telescopic rod 17 is fixedly connected between the outer shell 1 and the connecting plate 14. A spring 18 is sleeved on the outer wall of the telescopic rod 17. One end of the spring 18 is fixedly connected to one side of the outer wall of the outer shell 1, and the other end of the spring 18 is fixedly connected to one side of the outer wall of the connecting plate 14.

[0031] Specifically, the spring 18 between the outer shell 1 and the connecting plate 14 can buffer external forces, the telescopic rod 17 acts as a guide, and when the connecting plate 14 slides, it drives the guide plate 15 to be limited on the outer wall of the guide plate 13, and then the limiting plate 16 further guides the two sides of the connecting plate 14 to achieve a buffering effect.

[0032] Working principle: When using this TV back panel, first start the fan 8. The fan 8 draws outside air into the housing 1. During this process, the air is first filtered by the filter plate 9 to prevent dust and other impurities from damaging the internal components of the housing 1. After prolonged use, the filter plate 9 can be pressed and slid between the fixing plate 4 and the filter plate 9. The sliding of the locking block 10 then applies pressure to the spring 11, causing it to retract. When the locking block 10 has completely moved to the inner wall of the fixing plate 4, the filter plate 9 can be removed for cleaning or replacement. Installation only requires... When the filter plate 9 is put back in its original position, the spring 11 will no longer be under force and will rebound, thereby pushing the locking block 10 to move back into the interior of the filter plate 9, realizing the removal and installation of the filter plate 9. The filtered air continues to be delivered, and after being cooled by the heat sink 7, it is discharged into the interior of the outer casing 1. During this process, the cooling water in the cooling water tank 5 is circulated through the circulating water pipe 6, so that the cooling water is evenly distributed inside the heat sink 7, keeping the heat sink 7 cool. Finally, the air that has undergone heat exchange inside the outer casing 1 is discharged through the ventilation hole 2, achieving the effect of cooling and heat dissipation for the television.

[0033] In addition, the external force is buffered by the spring 18 between the outer shell 1 and the connecting plate 14, and guided by the telescopic rod 17. During this process, when the connecting plate 14 slides, it will drive the guide plate 15 to be limited on the outer wall of the guide plate 13. Finally, the limiting plate 16 further guides the two sides of the connecting plate 14 to achieve buffering.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
